This is an old post, but just coming across it, 2ML (Won Bin) in https://kisskh.at/255-autumn-tale wins as the best 2ML. I saw this when I was little with my mom, and still remember thinking that the 2ML out shining the main lead. He was WAY better than the ML.
More recently, I also liked the smart 2ML in Love Like the Galaxy. He wasnt better than the ML, and I'm glad that the ML got the girl, but I felt terrible for him.
